There are two types of chromatin, euchromatin and heterochromatin, that vary with the stages of the cell cycle. In particular, euchromatin with rich active genes localizes to the interior of the ...

A condition known as Robertsonian translocation occurs when the long arms of two chromosomes join together. The characterization of the fully sequenced and assembled fused chromosomes reveals a common ...

PHILADELPHIA – Human artificial chromosomes (HACs) capable of working within human cells could power advanced gene therapies, including those addressing some cancers, along with many laboratory ...

Cancer doesn’t evolve by pure chaos. Scientists have developed a powerful new method that reveals the hidden rules guiding how cancer cells gain and lose whole chromosomes—massive genetic shifts that ...

Researchers from Tokyo Metropolitan University have developed a suite of algorithms to automate the counting of sister ...

“We’ve known that tiny fragments of ancient DNA can survive for long periods of time,” said Dr. Marcela Sandoval-Velasco of the Center for Evolutionary Hologenomics at the University of Copenhagen and ...

A chromosome is a DNA molecule that contains genetic material. Sex chromosomes are chromosomes that affect your sexual anatomy and reproductive development. Most of us were raised with the idea that ...

Sex is determined in a variety of different ways throughout the animal kingdom. In mammals, it is determined genetically, not by temperature, as it can be in reptiles. Typically, females have two X ...
